IV. Prognostic significance of cytogenetics and genetic markers not detected by traditional karyotype analysis, with special respect to tyrosine kinase receptor mutations (such as fms-like tyrosine kinase 3 [FLT3]), retrovirus-associated deoxyribonucleic acid (DNA) sequences (RAS)- and nucleophosmin gene mutations along with CCAAT/enhancer binding protein, alpha (C/EBP) mutations.
